V souvislosti s evolucí přístupových sítí se v současné době stále častěji diskutují optické, případně kombinované opticko-metalické přístupové přípojky označované jako FTTx (Fibre to the X), kde optická část přípojek bude založena na některé z variant pasivních optických přístupových sítí (PON), nejčastěji na variantě GPON (Gigabit Passive Optical Network) či EPON (Ethernet Passive Optical Network). […]
The SC connector (short for Subscriber Connector, square connector or Standard Connector) mianly used in Datacom and telecom; GPON; EPON; GBIC, It features a 2.5mm Zirconia Ceramic ferrule and a push/pull coupling mechanism for a fast and reliable connection. The SC connectors are available for single mode UPC with blue boots, for APC with green […]
Optical fibre has incredibly low loss coupled with extremely high capacity, making it a unique transmission medium. From the point of view of the access network The Shannon Limit can effectively be ignored. Distance is not an inherent limitation as optical signals can travel 70–80 km before they need to be amplified. Instead the limitations […]
Splitter-based FTTx architectures are a compromise between cost and the flexibility of running fiber to every subscriber location. Instead of running fiber from the central office/ headend to every home like in a P2P arrangement, which is extremely expensive, splitter-based architectures run a single fiber from the headend/central office out to a central distribution point […]
